Preparation method of refractory material for tapping hole of converter
The invention discloses a preparation method of a refractory material for a tapping hole of a converter, the refractory material comprises a magnesia carbon brick body, a layer of pasty coating is sprayed on the surface of the magnesia carbon brick body, the coating thickness of the pasty coating is greater than or equal to 13mm, and the pasty coating is sintered at the high temperature of the converter. Compared with the prior art, the method has the advantages that the pasty coating sprayed on the surface of the magnesia carbon brick body is smeared, and the pasty coating is sintered at the high temperature of a converter, so that the production cost is reduced, fire-resistant repair of the magnesia carbon brick body at the tapping hole is realized, and the aperture of the magnesia carbon brick body is kept unchanged.
本发明公开了一种转炉出钢口耐火材料的制备方法，包括镁碳砖本体，在镁碳砖本体表面喷涂一层膏状涂料，所述膏状涂料的涂抹厚度≥13mm，在转炉自身的高温下，该膏状涂料完成自身的烧结。本发明与现有技术相比的优点在于：在镁碳砖本体表面喷涂的膏状涂料经涂抹施工，在转炉自身的高温下，该膏状涂料完成自身的烧结，降低生产成本，且实现对出钢口镁碳砖本体的耐火修复，保持镁碳砖本体孔径不变。
